Specification forming part of Letters Patent No. 41,888, dated Marcl1 8, 1864.-

.To aZZ whom, it' may concern.- l

Beit known that l, LUTHER HALL, 'of Boston, in the count-y of Suffolk and State of Massachusetts, have invented an Improved Peg- ])riving Machine, of which the following is a full, clear, and exact description, reference being had to the accompanying drawings, making part of this speciiicatiominwhich- Figure l is a view of my improved machine; Fig, 2, a vertical section through the case or body'of-the machine, showin g the parts within in elevation; Fig. 3, apartialelevation, with the part B removed to show the inclincs which operate the pin o; Fig. 4, a view of the-part B detached, with the switch attached thereto, and the sliding block G; Fig. 5, plan of the ring or yoke m, with thepin c; Fig. .6, detached view of the plunger, with the awl and knife. "Figs, 7 andS represent the switch d detached. v

My machine is particularly calculated for driving the pegs which are inserted at the time the shoe is being lasted to' secure the upper leather' temporarily to the inner sole and to the last. Such pegs are not driven regularly round the sole, as in ordinary peg work, but at irregular distances from each other. 0n this account, in lasting boots and shoes, thepegs have always been driven byhand, as the pegging-machines heretofore used would manifestly not be adapted'to the pur pose.

In my improved machine the descent of the plunger alternately makes a hole, and cu-ts oft' a peg, and drives it, so that by striking two blows upon the plunger without removing the instrument a hole will first be made, and a pcg Will then be driven into it.

To enable 'others skilled in the art to understand my invention, I will proceed to describe the manner in which I have carried it.out.

The body'or case A of the pegger is of metal. The awl is extricated from the leatherv by the spring C, andthe plunger is raised hyV th e leather, an din the latter case it must simply descend to the surface of the leather Without;` penetrating it. To accomplish this end, a small block, G, is made to slidefronroue end to the other of a slot, H, each time the plunger ascends. When it is at one endof the slot, the plunger, on being struck with a hammer, desccnds tothe end of its stroke', and the aw] enters -the leather, as seen at :v in Fig. 2, the

knife y, which is connected with the plunger and projects down from its end by the side of the awl, Fig. 6, at the same time splitting otl a peg,vwhich on the next ascent of the plun. ger .is projected by the india-rubber feedspring g in beneath the awl and driver. The same ascent ofthe plunger moves the block Gr4 tothe otherend of' the lslot H and imma diately beneath theboss I, projecting from the plunger. On the -next descent. of the plunger this boss strikes the block G, and the plunger is arrested at the moment when the awl reaches the surface of the leather, having driven the peg into the hole made on the previous descent of the plunger.

The motion of the block G in it's slot is et'-A fected every time the plunger ascends, as follows:A The spring E at its bott-om end rests upon the case ath, and at its upper end beneath a pin, i', projecting from the plunger. Above this pin is a ring or yoke, m, whichplays freely round the plunger, upon Whichit is kept in place by the pin 'i beneath-it and a shoulder, e, above it. This rin g has a projecting pin, c, which plays vertically in a recess in the part B and on one side or the other of the triangular switch d as the plunger moves up and down. The switch dis pivoted at a., Fig. 4, to the piece B, and has a forked projection, n, upon its upper side, which embraces a pin, t, on the block G in such mannery that as the switch is vibra-ted upon its pivot'the block is vibrate-d from Aone end to the other of thel slot.

'The vibration of the switch is effected as follows: Each time the piston descends the pi n c is guided into the center of the recess by the inclines w and z, and ou again rising it is guided by the switch to one side or they other of the recess, the pin itself shifting the switch and moving the block. 0n the next ascent of. the plunger the pin is guided to the opposite side ofthe recess andthe switch is vi- STEVENSOME MEL'..

vbrama in the 'opposite directibn, and thus umy block, which follows the mqtionsjof the switch, -is alternately moved 'to one.- end or the, other of its slot,as required.

VThe operation of the pegger is asfollows.

The innersole having been placed upon the last, the upper leather is drawn over it and the' instrument is placed upon the'point where a peg is required. The `lastfy ascent ,off the' i plungerhaving. left the block G upon that side ofgits slotiwhere it will notinterfere with the descent -of the boss I, when the plunger is struck by the hammer the awl penetrates the leather, and' at the same time the knife splits of a peg from the strip of pegfv'vood, and the pin cis guided into the center of the recess or opening in the case by one of the incl-ines, w or z. As the plunger rises this pin, being guided by the` switch. to the opposite side, turns the switch so as to shift the block G, and on theplunger being again struck by the hammer the boss VI strikes the block, and the awl, now acting as driver, forces' the peg v which was split o' bythe previous descent of the plunger. intothe hole just made.- As the pine again lrises itshifts the block from bc- 'lhxeath the boss '1, andon the instrument being moved to another place the operation may'be continued,l as before, each. twov blows of the hammer-upon the plunger making a hole andV driving a peg.

When the awl operates as a driver', the knife does not descend, low enough to split olf a peg; {The strip of peg-woodduring this operation restsagainst the driver,'and ltwould manifestly not answer-to allow-.the pegwood to feed'` in under vthe driver previous'to the next descent, as it is on'this descent that'the l'awl is to makethe hole. To prevent the pegwood from being fed at this time, theupward motionof the, plunger is interruptedby thepinr, so that the driver does 'not riseabove the peg-wood. 0n the next descent ot'gthe' awl to make a' hole thevknife splits oifa peg,

and lonthe plunger again ascendingthe pin c is guided to the side'ot'the recess oppositeto the pin r, and the driver rises suiciently high to permit'the pegcut oi on the previous descent to be fed beneath it, ready to be driven on the next descent ofthe plunger. The peg-y str'in is fed forward by they indiafrubber or Vother spring, g, in a well-known manner.' I

What I claim as my invention, and desire to secure by Letters Patent, as an improvemen in pegging-machines, is-

A1. interrupting the motion of the awl and employing it as a driver upon each alternate stroke, for the purpose described.

2. Interrupt-ing therupward motion of the .driver every other time it' ascends, toV prevent the feeding of the peg-stri p until after the peg is cnt o' and the hole is made to receiveit.

3. The combination ofthe boss I, the block G, the switch .17, and the pin c, or their equiv-` alents, operating as set forth, for the purpose specified i LUTHER HALL.
